Macs fan control does not work at all but fan speed go up randomly

So macs fan control worked before like a month ago but now it suddenly won’t work for some reason. I used other fan controlling software but none of them work. I did a hardware scan and it says there is a problem with the fan(error code PPF004) so maybe there is something wrong with the physical fan? But it does not explain the random fan speed spike which goes up to the average of 1000rpm. I don’t think there is anything wrong with the fan because it kind of works(?) but at the same time it doesn’t.

Edit: For clarification, I already cleaned the fan.

Yes you have a fan problem! The fan is likely clogged up with junk and/or the tach is messed up so the fan is not able to tell the logic board correctly what the fans rotation is (RPM).

Hi,

I recommend taking the laptop to a store so they can open it up and inspect the actual device and replace any parts as its sounds like the fan is clogged of dust and needs cleaning.

Hello, did you find the solution? I have the same problem and I already replaced the fan but it keeps running all the time at full speed and I can't control its speed with Macs fan control. I'll really appreciate any help :(
